Application filed January 3, 1921, Serial 110.434,66?. Renewed. November 1, 1921. Serial No. 515,692.

To all w izo/NL t may concern.' Y

Be itknown that l, Jnoo 5J. Penman@ a citizen of the United States, residing at New York, in the countyfand State of New York, have inventedz certain new-and useful Improvements inv Locks, of which the fol-y lowinO is a full clear and exact s Jeciiicatlon.

This invention relates to locksy of the type having longitudinally reciproeating*v bolts, and has for its object to provide an improved form off bolt of this kind which is jimmy proof and. will alsoresist attempts to saw through the main bolt. Another object is to provide a multiple bolt lock in which all of the bolts are simultaneously actuated. A further object is to provide an improved form of revoluble screw bolt yand- -keeper therefor.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute part of this specification, and then-more specifically delined in theV claims at the end of the description, f

ln the accompanying drawings,'wherein similar reference characters areused to designate'.corresponding parts throughout the' several views y Figure 1 is a vertical longitudinal section through alockand keeperinade in accordance with this invention.

Figure 2 is a horizontal lcentral longitudinal sectionthereof.

Figure 3 is a vertical cross section on the line Ill- III of Figure 1.

Figure 4 is a side elevation of the lock.

Figure 5 is an end elevation thereof.

Figure 6 is an end elevation of the keeper, and

Figure 7 is a cross section of the keeper taken through the arcuate slot for the pin on the threaded member thereof.

rlhe casing 1 of the lock is preferably made with a removable side plate 2 secured thereto by bolts 3, said casing being suitably attached to a face plate 4 fastened to the edge of a door 5 by screws 6 as indicated in Figure 1. The keeper has a face plate 7 secured to the door jamb by screws 8, and a tubular member 9 extending into theA jamb and hereinafter more fully described.

In the lock casing there are stepped guide lugs 10 for a double sliding bolt 11 made in U-shape with its ends adapted to be projected through openings 12 in the face plate 4 into openings 13 in the face plate 7 of the keeper. Between the upperand-lower larms of the double bolt there is arranged a revolublebolt 14 swiveledatits rearV end to the connecting member 15 of said double bolt as at 1G. The-forward end` portion of said revol-uble'bolt is screw-threaded, as at 17, and guides in a fixed collar -18 having internal threads to Afit and secured in Vanysuitable manner to the face plate 4.

Splined on the smooth rear end portion of the bolt 14is a beveled pinion 19 -joirrnaled in complemental projections 2O1and-21'on the casi-ngi and removable plate- 2, respectively, asbest shown in Figure 3. Meshing pinions 22and 2B, respectively, are mounted on the casing and said plate for rotating said pinion 19 and feeding the screw bolt through the fixed collar 18 whendesired, said side pinions 22 and 23 having key slots 24 accessiblefrom the sides'of the door 5 as at 25 in Figure 2.

- The key slot 24-shown in Figure 4 is triangular, but it will be-understood that a great variety of shapes for said key slots may be employed to prevent thelock being actuate by other than authorized persons.

In the tubular member 9 of the keeper there is loosely fitted an internally threaded sleeve 2G into) which the threadedend 17 of the revoluble bolt ,is adaptedto be turned when the latter is projected. from the lock casing as already describedand shown in Figure 2.. To insure the proper engagement of the threaded end of the bolt into the threads of the sleeve 26, said sleeve is cushioned on a spring 27 abutting against the closed inner end of the tubular member 9 and the inner end of the sleeve, so that the latter may yield until the threads of the bolt engage the threads of the sleeve. rlhe outward movement of the sleeve under the tension of the spring is limited by a projecting pin 28 on the sleeve extending into a slot 29 in the tubular member 9, said slot being made arcuate and extending part way around said member to allow the bolt and sleeve to rock back and forth so as to resist the cutting action of a saw should the same be introduced between the door and jamb in an attempt to saw through the bolt. The provision of the double armed bolt with its arms arranged above and below the threaded bolt adds to the security of the lock because one of the arms of said double bolt would have to be sawed through before access to the revolutie threaded bolt could be had. lt

will be noted that the double bolt is reciprocated with the revoluble bolt owing to the swivel connection 1G between them.

What claim is 2- l. The combination with a lock, of a screw-threaded bolt guided therein, means for feeding said bolt longitudinally in the lock for projecting the same, a keeper, and an internally threaded sleeve to receive the threaded bolt and mounted to turn in the keeper for the purpose specified.

2. rlhe combination with a lock, of a screw-threaded bolt guided therein, means for Yfeeding said bolt longitudinally in the lork to project the same, a keeper, an internally threaded sleeve movable axially in said keeper and adapted to have screw engagement with the bolt, and resilient means for pressing said sleeve outwardly toward the bolt.

3. The combination with a lock, oi a screw-threaded bolt guided therein, means for feeding said bolt longitudinally in the lock to project the same, a keeper, an internally threaded sleeve to receive the threaded bolt and mounted to turn in the keeper and move axially therein, and resilient means for pressing said sleeve outwardly toward the bolt.

4. The combination with a lock, of a screw-threaded bolt guided therein, means for feeding said bolt longitudinally in the lock to project the same, a keeper having a slot therein, an internally threaded sleeve mounted in the keeper and adapted to have screw engagement with the bolt, a projection on the sleeve extending into said slot, and resilient means for pressing said sleeve outwardly toward the bolt.

5. The combination with a lock, of a screw-threaded bolt guided therein, means :for feeding said bolt longitudinally in the lock for projecting the same, a keeper' having an arcuate slot therein, an internally threaded sleeve mounted in the keeper and adapted to receive the bolt, a projection on the sleeve extending into said slot, and resilient means for pressing said sleeve outwardly, said sleeve and bolt being adapted to turn in the lock and keeper, respectively, for the purpose speciiied.

6. The combination with a lock, of a revoluble and longitudinally movable bolt, and another longitudinally movable bolt connected to the revoluble bolt to move longitudinally therewith.

7. he combination with a lock, of a revoluble and axially movable bolt, and an axially movable bolt swiveled to said revoluble bolt lor axial movement therewith.

8. rl`he combination with a double armed bolt mounted for axial movement, of a revoluble and axial bolt arranged between the arms of said double bolt and connected thereto for axial movement therewith.

9. rlhe combination with a double armed i bolt mounted for axial movement, of a revoluble bolt mounted between the arms of said double bolt and swiveled thereto, and means for moving said bolts axially together.

10. rlhe combination with an axially movable bolt, of a revoluble bolt swiveled thereto and having a screw-threaded portion, an internally threaded collar fixed against rotation and adapted to feed the revoluble bolt together with the other bolt swiveled thereto axially when said revoluble bolt is rotated, and key-actuated means for rotating said revoluble bolt.

In testimony whereof I have signed my name to this specification.
